Our invention relates to dough molding machinery adapted for molding different lengths of loaves. a a i It is the object of our invention to providefa v 5 dough molding machine in which the batch of dough which is to be molded is first coiled in a forming pocket and is then positively discharged from coiling position after the co mpletion of the coiLfand in which the guidingis such'as to in- ,10 sure the coiled loaf remaining straight on th e discharge apron. t 3

vide a drum 'type molder in which the pressure plate and sideg uide members are formedinto one unit, which unit may -bereadily substituted 4 when it is desired to forma diiferent length oi' loaf by placing in the molder a combined pressure plate and side guidemembg'ers with .theside guide members arranged a different distance part. j It is a further object of 'ourinvention to provide a combined pressure plate and side guide sition relative to-the molding drumby first plac- 2; ing the unit in invertedposition above the drum and then swinging it radiallyaaround with the drum to its proper position for molding underneath the drum. I a

A further object of our inventionis to provide mechanism in combination with a molder for adjusting the pressure of the pressure plateand side guide units by a remote control located on the outside of the machine.- r c U t A further object is to provide a, series of adv justable dough coiling rollersin combination with a dough molding machine in which the dough coiling rollers are adjustably mounted with relation to each other, and'the'mechanism operating the adjustable rollers is-positioned on the v; outside of the machine so that, the rollers can to the rollers being had. 7 I

A further object is to provide a series of piv otally mounted sections of a'pressure plate on a be positioned by the mechanism'without access dough molder which will automaticallycompen-' sate for the change'of position of the pressure plate with relation to other.non-adjustableparts and thereby insure the continuity of the-space vb'etweenthe pressure plates and the, parts receiving the dough and'discharging it.

A further objectis to provide a self-adjusting mechanism for the chain drive; of the rollers which will keep the chain in properrcontactrelation with the driving sprocketsat'alltimes," in-' adjustment. t y.

In order to keep the chain 8'7 taut and in contact with all of the sprockets driven by it, we' have provided a novel self-adjusting chain tightener 90. A stud 91, fixed in the casing of the machine, rotatably supports an arm 92. On the arm. 92 there are two rotatably supported sprockets 93 and 93a, over which the chain 87 passes. At the end 94 of the arm a boss 95, with a hole 95a, slidably engages a rod 96. The rod has a threaded end 96a which screws into a threaded fixed boss 97 on the casing of the machine. Surrounding the rod is acompression spring 98 which bears against the face of the boss on the arm, and a washer 98a, which is held against the spring by an adjusting nut 98b. This nut adjusts the tension of the spring, so that it will always push the arm towards the right in Figure 4, and when any of the rollers are adjusted, take up any slack in the chain that would occur because of this adjusting.

When a load of dough comes on top of the rollers 58 and 58a, it will pass between them and be rolled into a sheet. This sheet will then pass between the lower rollers and 650,, where it will receive further rolling. The leading end of the sheet of dough then enters the pocket B, where it comes into contact with therollers 80, 81 and 72, which form it into a coil as shown at A. When the entire load has been coiled, the coiled dough will pass between the rollers 72 and. 81, and the roller '72 will eject the coiled dough which will pass along the apron down into the space between the pressure plate and the rotating drum. As soon as the coil-comes into contact with the drum, it will be rolled along the inner surface of the pressure plate and carried around to the discharge end of the machine,'where it will pass on to a conveyor to a desired operation in line with the completion of the baking.

Having thus described our invention, vwhat we claim as new and desire to secure by Letters Patent, is:- I p 1. A dough loaf molding machine comprising a drum and having a flexiblearcuate pressure board with side retaining members upon which said pressure board is adjustably supported, mounted as a demountable unit in said machine,. and means for adjusting the position of said pressure board relative to said drum, said means comprising pull bars and cam mechanism which said pull bars engage, said cam mechanism mounted in such position on said side members as to bear against said pressureboard.

2. A dough loaf molding machine comprising a drum and having a flexible arcuate pressure board with side retaining members upon which said pressure board is adjustably supported,

mounted as a demountable unit in said machine,

and means for adjusting the position of said pressure board relative to said drum, said means comprising pull bars and cam mechanism which said pull bars engage, said cam mechanism mounted in such position on said side members as to bear against said pressure board, and a rotary disc eccentrically mounting said pull bars.

3. In a dough molding machine, a drum, an arcuate pressure plate coasting with said drum and made up of sections, one of which isadjustable to and from the drum, means for entering dough between the plate and the drum at one end of the plate, means for receiving dough from between said plate and drum at the other end of said plate, another section of said plate, adjacent to this other end, being pivoted on said one section to swing toward and from the drum and having an extension which it maintains over said receiving means during its swinging. g

4. In a dough molding machine, a drum, an arcuate pressure plate coasting with said drum, side members, means supporting said plate on said side members for adjustment to and from the drum, actuating means at the axis of the drum, detachably connected to the adjustment means, and means detachably connecting said side members to the drum for swinging said plate and side members coaxially with the drum, whereby said plate and side members may be swung to operative 1 position under the drum or to a position over the drum for' detachment and removal therefrom.

5. In a dough molding machine, a drum, an arcuate pressure plate coacting with said drum, side members, means supporting said plate on said side members for adjustment to and from the drum,

. a casing, means connecting said side members together and detachably connected to said casing,"

actuating means mounted on the casing, detachably connected to the adjustment means, and.

said periphery for receiving dough from said pe-.

riphery, an arcuate pressure board extending around said periphery from one end of said mechanisms to the other, side retaining members extending along opposite lateral edges of said pressure board and adjustably supporting said pressure board, said pressure board and said side retaining members being mounted as a demountable unit in said machine, with said side retaining members lapping across the respective sides of the drum adjacent to the drum periphery so'as to prevent removal of the unit in direction along the axis of the drum, and said mechanism at both portions of the drum periphery being spaced from said periphery sufficiently to permit said unit to be moved arcuately. into or out of its operative position between the two mechanisms, through the space between said one mechanism and the drum periphery, and said unit being so mounted in the machine as to permit said arcuate movement, and the unit, when in its initial position for insertion into the machine, and, when in its final position for removal from'the machine, being sub-3 stantially inverted from its operative position be tween the two mechanisms.
